How ETH 2.0 Upgrade Will Completely Change Ethereum Network Performance and Security
The Ethereum 2.0 upgrade has brought revolutionary changes to the Ethereum network, significantly enhancing its performance and security. This upgrade transitions Ethereum from a Proof of Work (PoW) mechanism to a Proof of Stake (PoS) mechanism, greatly reducing energy consumption and making Ethereum more environmentally friendly. At the same time, the introduction of sharding technology has qualitatively improved Ethereum's transaction processing capacity, increasing the number of transactions processed per second from the original 15-20 to over 100,000. This not only improves network efficiency but also lowers transaction costs, making Ethereum more suitable for large-scale applications.
In terms of security, the PoS mechanism protects the network by requiring validators to [stake] ( ) ETH, which significantly increases the cost of attacking the network. Additionally, the introduction of sharding increases the redundancy of the network, allowing the entire network to function normally even if some shards are attacked.
